Jezža (crater)

Jezža Crater is a crater in the Argyre quadrangle of Mars, located at 48.8° S and 38° W. It is 9.1 km in diameter and was named after a town in Russia. Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact.
